Ingredients

3 cups Oreo crumbs

6 tbsp butter, melted

1½ cups heavy whipping cream, cold

½ cup powdered sugar

1 teaspoon vanilla extract

1 teaspoon espresso powder

16 oz semi-sweet chocolate, chopped

½ cup unsalted butter, melted (plus 1 tbsp for greasing the pan)

10 oz mascarpone cheese, room temperature

2 tablespoons powdered sugar

5 Oreo cookies (for garnish)

1 teaspoon unsweetened cocoa powder (for garnish)

Instructions

Step 1: Grease a 9½ inch pie pan with 1 tablespoon of melted butter or baking spray. Set aside.

Step 2: In a medium bowl, combine the melted butter with the Oreo crumbs and mix until fully combined.

Step 3: Firmly press the Oreo crumb mixture into the bottom and up the sides of the prepared pie pan. Use a measuring cup to shape it evenly. Refrigerate to harden the crust while preparing the filling.

Step 4: In the bowl of an electric mixer, whip 1 cup of heavy cream with powdered sugar and vanilla extract on high speed until it thickens and holds its shape. Set aside.

Step 5: In a microwave-safe bowl, combine the chopped chocolate, remaining ½ cup heavy cream, and melted butter. Microwave for 1 minute, stir, then microwave for another minute until the mixture begins to boil.

Step 6: Stir in the espresso powder until the chocolate is fully melted and smooth.

Step 7: Whisk the mascarpone cheese into the warm chocolate mixture until smooth and fully combined.

Step 8: Gently fold the whipped cream into the chocolate mixture using a spatula until fully incorporated.

Step 9: Pour the chocolate filling evenly into the chilled Oreo crust.

Step 10: For the garnish, whip the remaining 1 cup of heavy cream with 2 tablespoons powdered sugar until thick and holds its shape.

Step 11: Transfer the whipped cream to a piping bag fitted with a star tip and pipe decorative swirls over the pie.

Step 12: Top with Oreo cookies and lightly dust with unsweetened cocoa powder.

Step 13: Chill the pie in the refrigerator for 4-6 hours or overnight before serving to allow it to set fully.

Tips & Variations

Use a food processor to finely crush the Oreos for a smoother crust texture.

For a coffee flavor boost, increase the espresso powder slightly—but taste as you go.

Try substituting semi-sweet chocolate with dark or milk chocolate based on your preference.

Make individual chocolate pies using small ramekins or tart pans for single servings.

FAQs

Can I use a different cookie for the crust?

Yes, you can substitute Oreos with graham crackers or chocolate cookies for a different flavor and texture, but this will alter the classic taste of the pie.

Do I need an electric mixer to make this pie?

While an electric mixer makes whipping cream easier and faster, you can use a hand whisk if you have the patience. Just whip until the cream holds soft peaks.
